摘要: 为揭示云斑天牛(Batocera lineolata Chevrolat)对气味分子的识别机制,通过荧光结合试验和葡聚糖凝胶G75(Sephadex G75)层析研究了云斑天牛对气味分子的识别情况,并对云斑天牛气味结合蛋白进行了分离纯化。结果表明,云斑天牛气味结合蛋白能与荧光探针N-苯基-1-萘胺(N-phenyl-1-naphthylamine, 1-NPN)产生荧光结合,云斑天牛触角部位的总蛋白提取液中存在pro. Ⅰ-Ⅻ(Protein Ⅰ-Ⅻ)12种大分子粗提蛋白,这12种大分子粗提蛋白经Sephadex G75纯化后,得到1种能与荧光探针1-NPN产生荧光结合的纯化蛋白pur-pro. I(purified protein I)。纯化蛋白pur-pro. I分子质量约为15.2 ku,对应为大分子粗提蛋白pro. Ⅻ(Protein Ⅻ)。鉴定认为,分离纯化蛋白pur-pro. I是云斑天牛的一种气味结合蛋白。

Abstract: The fluorescence binding assays and Sephadex G75 chromatography were conducted to investigate the recognition of odorants by Batocera lineolata Chevrolat. Additionally, one of the odorant binding proteins in B. lineolata was isolated and purified. The results showed that the odorant binding protein of B. lineolata could combine with fluorescent probe(N-phenyl-1-naphthylamine, 1-NPN). Besides, twelve kinds of macromolecular crude extract protein(pro. Ⅰ-Ⅻ, Protein Ⅰ-Ⅻ)were found in antenna of B. lineolata. When the 12 kinds of macromolecular crude extract protein were isolated and purified by Sephadex G75, a purified protein(pur-pro. I, purified protein I)was found, and it could also combine with fluorescent probe(N-phenyl-1-naphthylamine, 1-NPN). The relative molecular weight of pur-pro. I was approximately 15.2 ku, and it was pro. Ⅻ(Protein Ⅻ), when contrasted with all kinds of macromolecular crude extract protein. All above, it declared that the isolated and purified protein pur-pro. I was one of the odorant binding proteins in B. lineolata.
